DJHW/HZ‑27‑100S‑C is an ultra‑compact lightweight airborne MESH ad‑hoc video‑data integrated communication module. It adopts a 2T2R dual‑channel RF architecture with 2×27dBm transmit power, adjustable from ‑40~27dBm in 1dBm steps, supporting both MIMO and CA (Carrier Aggregation) working modes. It achieves 30 km maximum single‑hop LOS range in open conditions with 200 m air‑ground elevation difference, delivers 95 Mbps shared network throughput and supports large‑scale networking up to 128 nodes. The average one‑way ping latency for two‑node networking is less than 15 ms, and cold‑start access latency for new nodes ≤30 s.
With dimension of 56.0×57.0×14.9 mm (excluding RF connectors) and weight ≤58 g, the module integrates a temperature‑controlled cooling fan and accepts wide‑range DC 9‑36 V power input. It is equipped with dual 100 Mbps Ethernet ports, 2‑channel RS232, 1‑channel TTL and dual MMCX RF interfaces, and supports GPS 1PPS pulse‑per‑second input. Three optional encryption algorithms AES128, ZUC and SNOW3G are available. It features interference detection, adaptive modulation, distance‑based transmit‑power adjustment and automatic retransmission of erroneous packets. The embedded WEB‑UI supports network‑topology visualization, SNR / BER monitoring, as well as local and remote OTA firmware upgrade. Optimized for payload‑limited platforms such as UAVs and mobile robots, it enables integrated wireless backhaul of video, control commands and sensor data for emergency communication, power‑line inspection and offshore‑monitoring scenarios.

DJHW/HZ‑27‑100M‑C belongs to DJADHOC 2nd‑generation MESH ad‑hoc airborne‑module family. Based on OFDM wireless communication technology, its flat‑system architecture effectively reduces end‑to‑end latency. Targeting payload‑constrained platforms such as UAVs and mobile robots, it delivers integrated wireless transmission for HD video, flight‑control commands and sensor data in public‑network‑denied areas.
The module supports multi‑hop MESH networking. Mobile nodes rapidly re‑join the network when re‑entering coverage after temporary disconnection. Routing tables update automatically upon topology changes, and isolated sub‑networks can merge quickly. Equipped with automatic frequency‑hopping, adaptive transmit‑power and packet‑retransmission anti‑interference capabilities, it is a preferred lightweight communication solution for aerial relay, field inspection and emergency‑rescue applications.
